Problem with Spotlight taking huge time to reindex a drive

Hello,

I have a problem reindexing a hard drive which contains a partition of 902.43 Gb available and 106.46 Gb free. Reindexing begins showing one hour of work, then it gets longer until more than 7h00 to wait, and it seem to stop. I've used the disk utility to check the drive, and there is no problems with it. I've also used Onyx to do the maintenance tasks (repairing permissions, ...). I don't know where to look.

Thank you
